WP1130 (856243-80-6) is a novel DUB inhibitor directly inhibiting USP9x, USP5, USP14 and UCH37 inducing rapid accumulation of polyubiquitinated proteins. Triggers tumor cell apoptosis.1 Blocks Jak2 signaling via Jak2 ubiquitination.2 WP-1130 causes ablation of the oncogenic transcription factor ERG in prostate cancer cells.3 See methyl analog WP1066.
(2E)-3-(6-Bromo-2-pyridinyl)-2-cyano-N-[(1S)-1-phenylbutyl]-2-propenamide can be used in biological study of drug screening and proteomic and metabolomic profiling to identify drug action mechanisms of breast cancer impaired pathogenicity.
